About — Toll Stack

The operator

My name is Bill Eisenhauer. I've been building production software for over 40 years — the kind where getting it wrong costs money, not just uptime.

I started on enterprise systems in the late '80s. Mainframes, transaction processing, the infrastructure that banks and airlines ran on. The systems weren't glamorous, but they were real: real data, real money, real consequences when the code was wrong.

Then four years at Ernst & Young, one of the Big Four consulting firms. That's where I learned how businesses actually work — not just the technology, but the operations, the money flows, and the places where value leaks between departments without anyone noticing.

After that, startups. Employee #1 at a GPS tracking company, where I learned what it means to build everything from nothing. Then an early engineer at a Silicon Valley company that grew from a small team to a $2 billion public company. I watched the entire arc — from scrappy product to IPO — and learned that the difference between companies that scale and companies that break is almost always the operations, not the technology.

The Origin Story

The old plan (my version)

When I left the corporate track, I did what every technical builder does: I started planning SaaS products.

I went all in. Created a holding company called Plenty of SaaS — registered the domain, plentyofsaas.com, set up the corporate structure. The plan was to build and operate a portfolio of small SaaS products. Vertical tools for underserved niches. The classic indie hacker playbook, but with enterprise experience behind it.

I knew funnels. I knew email. I knew landing pages and data and conversion optimization. I knew how to build production-grade systems. On paper, I had every advantage.

And then I hit the same wall everyone hits.

Build the product. Build the audience. Build the distribution. Build the support. Build the operations. The creating never stopped. And each product — no matter how well-built — needed its own audience, its own marketing, its own customer success. The holding company wasn't holding a portfolio of assets. It was holding a collection of full-time jobs.

That's the bog down. I recognized it because I'd seen it at scale — companies with hundreds of engineers still struggling with the same problem. Creating everything yourself consumes the two things you can't manufacture: time and energy.

The new plan

The realization wasn't dramatic. It was quiet — the way most important things are.

I noticed that the skills I'd built trying to launch SaaS products — the funnels, the email sequences, the landing pages, the data analysis, the conversion optimization — those skills were the same ones that businesses with existing traffic desperately needed but didn't have.

Creators with audiences but no capture infrastructure. Experts with traffic but raw affiliate links going nowhere. Businesses with products but no bridge between their offers and the people who'd buy them.

The gap was everywhere. And the skills to fill it were the exact skills I'd accumulated across 40 years of building systems — refined by the SaaS attempts that didn't work out the way I'd planned.

Plenty of SaaS became the un-SaaS. Same holding company. Same infrastructure skills. Completely different architecture. Instead of building products and hoping for distribution, I started building the distribution infrastructure inside businesses that already had the products and the traffic.

The toll position model.

Why Toll Stack exists

I built Toll Stack because nobody showed me this option. I spent years assuming the only path was build-your-own-everything. The SaaS bros, the indie hacker Twitter threads, the startup incubators — they all run the same playbook. And for some people, it works.

But for the technical builder who's great at infrastructure and operations, who can wire up email sequences and conversion funnels in their sleep, who understands data and systems — there's a different architecture. One that skips the product creation entirely and goes straight to the piece you're already good at: the bridge between traffic and revenue.

Everything published here — the Playbook, the articles, the tools, the community — documents this model from the inside. Not theory. Not guru marketing. Specific mechanics, specific math, specific operations from someone who runs the thing.
